The role of retinol saturase enzyme and adenosine A3 receptor in skeletal muscle development and regeneration
Tarban, Nastaran; Sarang, Zsolt; Molekuláris sejt- és immunbiológia doktori iskola; Általános Orvostudományi Kar
Following skeletal muscle injury, the regeneration begins with local inflammation, which is accompanied by the removal of dead cells. Phagocytosis of dead cells regulates the inflammatory program in macrophages (Mϕ) by promoting the transformation of inflammatory macrophages into “healing” macrophages. The pro-inflammatory cytokines initiate the activation and proliferation of muscle stem cells, called satellite cells, while growth factors, produced by healing macrophages drive myoblast differentiation, fusion, and myotube growth. Therefore, impaired phagocytosis or inflammation can lead to decreased muscle regeneration. The oxidoreductase enzyme retinol saturase (RetSat) is required for proper Mϕ phagocytosis while A3 adenosine receptor (A3R) was shown to modulate inflammatory responses. Therefore, our aim was to investigate the impact of RetSat enzyme and A3R deficiency on skeletal muscle development and regeneration in mice.
Tibialis anterior (TA) muscle damage was induced by intramuscular cardiotoxin (CTX) injection. Muscle fiber cross-sectional area (CSA), collagen deposition, and the extent of tissue necrosis were measured to evaluate the regeneration process. Flow cytometric analysis was used to quantify intramuscular leukocyte infiltration and detect SCs. Gene expression was measured in total muscles and muscle-infiltrating CD45+ cells. In vivo muscle force measurements were used to determine the impact of A3R ablation on physical performance.
We found that RetSat ablation did not affect the body and TA muscle weights. In addition, the structure and the fiber size of the regenerating muscles ultimately were similar in both strains. In accordance with the previous findings, the in vitro phagocytosis assay showed lower phagocytic capacity of the Mϕs in RetSat−/− mice. Parallel with this, we detected decreased milk fat globule-EGF factor 8 protein (MFG-E8), arginase 1, and neuropeptide Y expression and increased IL1-β and nitric oxide synthase expression in muscle-derived CD45+ in RetSat−/− mice. There was a decreased CD45+ cell infiltration in the regenerating muscles of RetSat−/− mice. However, the size of the necrotic areas in the regenerating TA muscles was similar between the two mouse strains. In line with this, we detected a robust MFG-E8 expression in the regenerating TA muscles of both strains. A3R ablation did not affect body and muscle weights, but a higher percentage of bigger muscle fibers was detected in fast twitch muscles of A3R−/− mice, as well as decreased muscle strength in mice. There was an increased CD45+ cell infiltration in the regenerating muscles of A3R−/− mice and these mice exhibited a more rapid clearance of necrotic tissue and a reduced collagen 1 deposition during TA muscle regeneration. Moreover, we detected a significantly increased myofiber CSA in the regenerating muscles of A3R−/− mice at day 22 post-injury. We have found that in the RetSat−/− mice, there are multiple compensatory mechanisms between the cells that participate in the skeletal muscle regeneration which ultimately results in normal muscle repair in the absence of RetSat enzyme despite the observed decreased Mϕ function. In the case of adenosine A3R, our data support the role of this receptor as a negative regulator of both injury-related regenerative inflammation and muscle fiber growth in the TA muscle. Consequently, the inhibition of A3R may hold therapeutic promise for enhancing skeletal muscle regeneration after injury.

Representation of Genderqueer Identities in Fictional and Nonfiction Narratives
Tóth, Karolina; Papp, Fruzsina; DE--Bölcsészettudományi Kar
This paper examines the representation of genderqueer identities in The Honeys by Ryan La Sala and Gender Queer: A Memoir by Maia Kobabe. These works focus on genderqueer people’s struggles in everyday life. The novels focus on family related problems, self-acceptance, pronoun change and the use of gender inclusive language in fictional and autobiographical narratives. Since one’s sexual or gender identity is often not discussed at home or at school, the first- time young people encounter LGBTQ identities are in popular culture. These identities are represented in novels, comics, TV series or films. It is necessary that these young people see good representation of identities and have the opportunity to find the language that is inclusive to their gender identity.
The Representation of Obsession Through Joe Goldberg’s Character in YOU, Season 1 (2018)
Teleki, Emese; Hudácskó, Brigitta; DE--Bölcsészettudományi Kar
In the first season of the Netflix series YOU (2018), the theme of obsession takes center stage, offering a deep dive into the complexities of interpersonal relationships and the darker layers of romantic pursuit. My thesis attempts to unfold the multifaceted portrayal of obsession through the character of Joe Goldberg, exploring the psychological factors that drive his obsessive behavior in both romantic and non-romantic contexts. Drawing on Joe’s troubled childhood marked by neglect, abandonment, abuse, rigid discipline, and control, I explore how these formative experiences serve as a backdrop to his obsessive tendencies. The series vividly portrays Joe’s relentless quest for love, driven by distorted perceptions of affection and control, which manifests in possessive behaviors, stalking, manipulation, and the idealization of his romantic interest, Guinevere Beck. In a non-romantic context, the series also highlights Joe’s obsessive instincts toward protecting Paco, his neighbor’s son, as well as his attempt to project the illusion of an upstanding member of society that masks his underlying persona. The male gaze and the protector tropes are also examined, framing Joe’s obsessive behavior as justified while manipulating audience perceptions.
The Figure of the Mad Woman in Charlotte Brontë's Jane Eyre
Szilágyi, Kamilla; Kiss, György; DE--Bölcsészettudományi Kar
Jane Eyre by Charlotte Brontë (1847) is one of the most influential books in the Victorian period, especially in women’s history, with its groundbreaking female protagonist who is not the usual passive female character but takes her future into her own hands. Considering that Charlotte Brontë wrote about strong female characters it is not surprising that she touches upon the Victorian madwoman issue. By looking at the historical background of insanity within women in the nineteenth century, and examining Bertha Mason’s madness and personality, I investigate Jane’s behaviour in comparison to Bertha's in my thesis, with special attention on racial and social similarities and differences. In the first chapter, I introduce the historical background of women and mental disorders in the nineteenth century to understand how Victorians treated mad women. Secondly, I present Bertha Mason, the main "mad woman" in Jane Eyre, who is locked in the attic from the moment she is deemed mad. Thirdly, I describe Jane Eyre, the protagonist of the novel, explore her mental state in relation to Bertha’s and argue that she could have received the same harsh treatment if it was not for her race and Rochester’s love for her. Lastly, I compare Bertha and Jane, arguing that Bertha is Jane’s dark double and examining how Bertha executes Jane’s secret desires.
The United States and the Pacific Theater in the Second World War
Szabó, József; Venkovits, Balázs; DE--Bölcsészettudományi Kar
As a result, the purpose of this thesis is to discuss how crucial the participation of the United States in the Second World War was, and its main goal is to elaborate on how its entry changed the outcome of the entire war. Starting from the Battle of Pearl Harbor (after which the U.S. joined the war) and ending the thesis with the discussion of dropping the atomic bombs and the signing of the peace treaties (which ended the First World War). Its narrative will be unfolded through three chapters, giving the reader a relatively detailed picture about the events. The first chapter is an introductory part, which provides insights into the Interbellum Era (or Interwar Period) and the circumstances of the beginning of the Second World War. The second chapter is based around the overview of why and how the United States joined the war (as a result of Pearl Harbor) and the most important battles at the Pacific Theater are introduced, explained with a focus on why they are important regarding the outcome of the war. And this will start the third and closing chapter, which delves into the deployment of atomic bombs, the ending of the Second World War (including the Peace Treaties). Together, these chapters provide a narrative that reflects on how the United States’ entry into the war itself changed the outcome of the war.
The History of African American Women During Slavery Times America
Marosán, Cynthia Patricia; Krisztán, Daniella; DE--Bölcsészettudományi Kar
This thesis aims to analyze the experiences and legacy of African American women. During slavery, they had to face multiple challenges due to their double burden. The conditions of servitude not only affected Black women physically but also mentally to a great extent. Hence, their trauma has been passed down on future generations in the form of inter-/transgenerational trauma, resulting in various mental health issues like depression, which many Black people suffer from today. In addition to this, African American women's contributions to causes like abolitionism and the development of education have been acknowledged, as well as that their cause in general is of great contemporary relevance and importance. To put an end to the systemic discrimination against not only Black women but also African American people in general, a change in perspectives and broad support is required.
When the Foreign Finds Familiarity: The English and Hungarian Translations of Culture-Specific Items in Han Kang’s Human Acts
Molnár, Dorka; Hudácskó, Brigitta; DE--Bölcsészettudományi Kar
In my thesis, I aim to explore the possible translation techniques of culture-specific items through examining the Hungarian and English translations of the South Korean author, Han Kang’s novel, Human Acts. This study aims to show an insight into the historical background of translation as well as its relationship with cultures. I examine the foreignizing and domesticating methods widely used in translating culturally significant texts. Through the extended reading of the book’s chapters, I identify the specific methods used in translating culture-specific items and compare the two translations in light of their translators’ solutions.
Being a Detective is a Manly Job
Tóth , Borbála; Hudácskó, Brigitta; DE--Bölcsészettudományi Kar
The literature of the 19th-20th century featured strong female characters who served as role models for oppressed women in patriarchal societies. Female detectives, often seen as unconventional, emerged as a response to the feminist movement. This thesis explores the first wave of feminism and its impact on literature, examining how it influenced attitudes towards duties and roles. It also highlights the struggle for women to find their place among men and their role in law enforcement. The series Miss Scarlet and the Duke illustrates the ideal woman image in the 19th-20th century and draw attention to her aim and methods. The thesis aims to prove that women are equally useful in law enforcement due to their unique characteristics.

Berdnichenko, Valeriya; Balogh, Erzsébet; DE--Bölcsészettudományi Kar
The purpose of this paper is to critically assess cultural representations in three English Language Teaching textbooks used in Kazakhstan's secondary school curriculum. Using Yuen's model of cultural representation as a theoretical framework, the study will undertake a complete content analysis to evaluate the presence and type of cultural portrayals in these textbooks. This thesis delves into the comparative content analysis of three ELT utilized in the Kazakhstani secondary school curriculum. The study aims to explore the prevalence of representations of cultures within these textbooks and to ascertain which cultural dimensions are more frequently portrayed in each. Specifically, the research seeks to address the following questions: What is the frequency of cultural representations in the three English language coursebooks? According to Yuen’s model, which category of cultural dimension predominates in each textbook? Do the selected textbooks provide a balanced representation of cultures, considering whose cultures are depicted?
The Marginalization of Women in Hollywood: Exploring Fame, Race, and Gender in Taylor Jenkins Reid’s The Seven Husbands of Evelyn Hugo
Apáti, Jázmin; Papp, Fruzsina; DE--Bölcsészettudományi Kar
This thesis seeks to explore Taylor Jenkins Reid’s novel, “The Seven Husbands of Evelyn Hugo”, more precisely the character of Evelyn Hugo, by exploring her journey from underprivileged background to stardom and the difficulties that accompanied her experiences in the film industry. By placing Hugo’s life story in the context of the new Hollywood era, marked by changing power dynamics and cultural transformations, the analysis highlights the pervasive influence of patriarchal norms and beauty standards on women in the public sphere. Central to this analysis is the exploration of feminist themes embedded in Hugo’s narrative arc, who is is presented as a symbol of female agency and resilience, challenging traditional gender roles and social expectations through her quest for agency. In addition, it examines the portrayal of Hugo as a flawed but resilient figure whose actions and decisions are shaped by the constraints of her environment and the relentless pursuit of her ambitions. Through a synthesis of literary analysis, feminist discussion and historical context, this thesis aims to provide a comprehensive understanding of “The Seven Husbands of Evelyn Hugo” and offers a reflection on the enduring relevance of feminist discourse in contemporary society. By exploring the intersection of fame, race and gender, the thesis also explores the ongoing struggle for gender equality and reflects on the importance of diverse representation in Hollywood.

Where’s My Playboy Bunny Outfit?
Uszkai, Patrik; Orosz Réti , Zsófia; DE--Bölcsészettudományi Kar
Games – online, offline, paid, and free in worlds of fantasy lands and cities filled with human bodies have been analysed to examine and gather the most prominent trends in bodily representation. For this purpose, the very core of the body had to be defined, how we see them, and how are they represented in a medium that gains inspiration from films yet also draws on a very different toolkit. While movies proved to be a good starting point, video game bodies differ on many levels from human bodies that appear on screen. In addition, not only bodies complicate the matter, but the medium as well: the core element that we are in control of one body inside game world, different camera views appear as we play and encounter cutscenes, and the added element that these bodies are not just there for solely aesthetic or story purposes, but for gameplay further complicate how we view them. That being said, the dominant trend that can be identified within single-player games is one of rigid, hypersexual bodies, carefully constructed within an idealised realism, infused further with other gendered roles. In case of online games, the same hypersexual tendencies can be observed, taken even further, and removing even that thin layer of humanness to maximise profit and player satisfaction in visual pleasure provided by bodies and commodity fetishism.
